If all machines are on their appropriate subnets and use the
central server as their default gateway you don't need to
proxy_arp.

All the directly attached networks should be known by their netmask
and shouldn't need explict routes.

If you do need to add routes through other gateways you can use the
Redhat/fedora GUI tool (system tools/network) and add the routes
using the 'route' tab of the 'edit interface' screen on the interface
facing the gateway.  Then the system will automatically add/remove them
as that interface goes up/down.
